"The detector detected the overflow of methane molecules!" A short alarm sounded in the main control room.
The busy people immediately put down their work and locked their eyes on the flashing warning light.
This alarm is both a sign of danger and a symbol of success.
This means that the test well is close to the storage area of flammable ice.
"Pay close attention to the gas spill situation!" Sun Wentong said immediately, "Report the amount of gas spill at any time!"
"clear!"
"Be ready for cementing operations at any time!" Sun Wentong issued the second order.
On the deck, workers in the cementing operation team were nervously transporting various materials and conducting pressurized inspections of the cement cementing manifold. All instruments and equipment went through another round of inspection to ensure that everything was faultless.
The drilling work continued in an orderly manner. Everyone stared at all the data on the big screen with wide eyes. Although the main control computer would alarm in case of danger, almost everyone was silently calculating these data in their hearts.
bring results.
A few hours later, the alarm sounded again: "The gas leakage has increased and reached the first level!"
The first level means that the current drilling has penetrated deep into the combustible ice ore layer at the trial mining point, which means that the current drill bit is surrounded by combustible ice ore bodies.
This is the first time that Chinese offshore workers have brought engineering mining tentacles deep into the combustible ice deposits on the seabed.
"Attention all on board, prepare for cementing operations now!" Sun Wentong immediately broadcast on all channels of the Blue Whale.
The cementing operation means that the first test drilling in the Shenhu Sea Area has completed the most difficult first step, creating a channel on the seabed tofu residue. The rock formation problem that worried Professor Huang the most has finally been solved.
The near miss was lifted, and the weight of hundreds of tons sat firmly on the rock formation, without causing additional pressure on the entire rock formation.
Of course, the most dangerous time has not passed yet. The cementing operation is also the top priority of the trial mining work. If you want to ensure the stability and safety of the trial mining work, the cementing operation must be timely and effective, otherwise the hidden dangers will be extremely serious.
of.
The intense work of the Blue Whale in the past few days was all for today's cementing operation. After more than a hundred experiments at sea and on land, the cementing fluid proportions finally developed were finally put to use.
As soon as Feng Chen got the news, he immediately rushed to the platform where the cementing manifold was located. The cordon had been set up. Although he was the coordinator in charge of the entire system, he could only stand outside the cordon and watch from a distance.
Watch the operator work.
This is only a thousand meters deep on the seabed. For a cement cement manifold that can reach the world's leading 30,000 psi, there is no pressure at all. It can even be said that this is not even a killing of chickens. I am afraid it can be called a...
Kill the chicken with a guillotine.
After a series of drilling fluid flushing, isolation fluid injection, and overall inspection of the entire drilling, the cementing fluid injection work officially began.
These carefully prepared cementing fluids quickly entered the seabed more than a thousand meters deep through the complex pipelines in front of them, establishing a solid channel in the loose rock formations connecting the Blue Whale to the combustible ice reservoir on the seafloor.
This is the basis for the Blue Whale's trial mining work. Only if this passage is unobstructed can the flammable ice hidden in the rock formations deep in the sea can smoothly reach the sea surface and become the Blue Whale's bag.
When the cementing operation was rapidly underway, Feng Chen saw several workers on the crane on the right side of the Blue Whale who were also busy.
He looked at the Blue Whale schedule registration form in his hand. This is the trial production headquarters' deployment of seabed topography, gas detection and various seabed hydrological monitoring equipment around the trial production well.
These equipment will operate underwater for a long time, constantly monitoring various changes around the seafloor during the trial mining period, especially whether there is the escape of methane gas and changes in the seabed rock formations, etc., which are related to changes in the entire trial mining process.
Together with various sensors on the Blue Whale and various monitoring equipment inside the test well, they build an integrated environmental safety monitoring system that can monitor the temperature, pressure, methane concentration and seabed stability parameters around the entire test well.
Comprehensive, real-time monitoring of the entire process.
This system can solve various potential safety hazards that may occur during the trial mining process to the greatest extent and ensure the safe and effective conduct of the trial mining.
The most important thing is that after mining, the environment of the Shenhu Sea Area can be continuously tested to ensure the environmental protection of the entire trial mining process and lay a solid foundation for formal production in the future.
And through these testing equipment, we can solve the problems that may occur during the trial mining process, and conduct a comprehensive design of the final mining well plan through optimized design based on the seabed topography characteristics, engineering geological characteristics, etc. in the combustible ice area.
, to avoid methane leakage and other situations.
Technical experts carefully screened the various data returned by the detection instruments to study and judge the situation on the seabed.
At the same time, the drilling team's cementing operations are also in full swing. Although the current seawater depth is only about 1,200 meters, it is still inferior to the Blue Whale's 3,500-meter deep seawater drilling capability.
far away.
The team members still dare not relax at all. After all, this is already a deep sea, and there are only a handful of countries in the world that can carry out drilling operations on such a deep seabed.
With the assistance of Blue Whale's powerful engineering equipment, the cementing operation went very smoothly with almost no obstacles. This made Feng Chenyi, who had been worried, finally breathe a sigh of relief.
When the cementing operation was announced to be completed, Feng Chenyi finally showed a satisfied smile on his face.
In addition, the hydraulic drive system, which has been tested several times through the sampling process, also performed outstandingly, greatly reducing the work intensity of the drilling team and improving work efficiency. Otherwise, they would not be able to complete drilling in the entire Shenhu Sea Area in such a short period of time.
Sampling work.
Although the trial mining mission has not yet started, the performance of the Blue Whale is particularly outstanding. The power, drilling and hydraulic systems all performed almost perfectly, which made Sun Wentong full of praise.
An oil and gas veteran like him with decades of mining experience knows as much about drilling platforms as designers like Feng Chenyi, especially since they can judge the quality of the platform based on their own feelings during use.
, this is the evaluation of end users, which is much stronger than the comments of many experts and scholars.
The outstanding performance of the Blue Whale. After all, this is an important weapon that he personally participated in the design. Feng Chen felt a sense of pride when he walked on the platform. Many experts and scholars involved in the trial mining work came to congratulate him. For them,
It is said that a platform with excellent performance will have the effect of getting twice the result with half the effort for their research work. Everyone has high hopes for the upcoming mining plan.
